[ https://issues.jboss.org/browse/JBIDE-26161?page=com.atlassian.jira.plugi... ] Martin Malina commented on JBIDE-26161: --------------------------------------- I wanted to figure out what was the problem with the mac slaves so that Nick had to use mac_xhyve. So I set the job to use dev-platform-mac-1 or 2. And I saw errors like these: {code} 11:59:26 [ERROR] Invalid extension descriptor for org.eclipse.tycho:tycho-maven-plugin:1.2.0: error in opening zip file 11:59:26 java.util.zip.ZipException: error in opening zip file {code} It felt familiar, I thought I was dealing with something similar not that long ago, but couldn't find it. And then it hit me: It was a problem with wrong maven repo setup. For example see this: {code} 11:59:57 [WARNING] Could not validate integrity of download from https://maven.repository.redhat.com/org/jboss/tools/parent/4.9.0.AM1-SNAP... {code} If you look at the url, it will redirect you to this page: https://access.redhat.com/maven-repository The main issue here is that there was a repo defined with this url: http://maven.repository.redhat.com/ Instead of: http://maven.repository.redhat.com/ga I fixed it for all the slaves by replacing the settings.xml files with this: https://gitlab.mw.lab.eng.bos.redhat.com/dev-platform/mwqa-cloud-slaves/b... {code} $ for i in domek.tpb.lab.eng.brq.redhat.com dev-platform-mac2.mw.lab.eng.rdu2.redhat.com bigmek.tpb.lab.eng.brq.redhat.com zamek.tpb.lab.eng.brq.redhat.com dev-platform-mac1.mw.lab.eng.rdu2.redhat.com; do scp /Users/rasp/Downloads/settings.xml jbossqa@${i}:.m2/; done {code} -- This message was sent by Atlassian JIRA (v7.5.0#75005)
